Description

RELATED APPLICATIONS
• This application claims benefit of U.S. Provisional Application Ser. No. 60/660,500 filed Mar. 10, 2005 entitled “Transmittable Digital Product and Label Data,” which is incorporated herein by reference.
BACKGROUND OF THE INVENTION
• The present invention relates generally to the field of digital labels and tags for products. It is typical for the manufacturer of a product to affix a label to the product which bears the manufacturer's brand name or logo. Labels are also used to provide product information and information about the manufacturer of the product. Because labels are typically small, they can carry only a limited amount of information. Therefore, it is not at all uncommon to find two or more labels affixed to different locations of a single product. For example, a product may carry a brand label which is placed in a visible location, and interior labels to give product information. However, there is a small, finite limit to the number of labels which can be applied to a product without cluttering the product.
• In the past, labels have served as merely static and passive devices to convey label information that is fixed in time, and have not been used to expand the functionality of the product. Animated designs and logos are not possible with conventional woven, printed or stamped labels. Also, conventional labels cannot display information which may change over time, or user-specific information.
SUMMARY OF THE INVENTION
• The present invention is a digital label for products that can be programmed to store, process, transmit and display information including label information and user-specific information. The digital label can also store authentication data to authenticate the product. The digital label includes a processing circuit, a memory for storing label information, and a display for displaying label information. An extensible program is stored in memory and is configured to execute user-defined applications or program code to extend the functionality of the digital label. In one embodiment of the invention, the extensible program comprises an operating system program with an application interface that allows development of custom applications by the manufacturer, retailer, or user to expand the functionality of the digital label. User-defined applications enable the digital label to receive, store, and process user-specific information, and to communicate and work other devices.

DETAILED DESCRIPTION OF THE DRAWINGS
• Referring now to the drawings, and particularly toFIG. 1, adigital label10 for products is shown and indicated generally by thenumeral10. For purposes of this application, the term “digital label” means a device having a display that functions principally as a means of identification that is attached or affixed to a product to designate its origin, owner, manufacturer, contents or ingredients, use, etc. The term “label” is used in the common sense to mean a device that is distinguishable from the product to which it is affixed and not a typical or inherent feature of the product. For example, a computer monitor and a display for a consumer electronic device (e.g., watch, cell phone, camera, etc.) are not considered to be “labels’ as that term is used herein because the displays are inherent product features.
• Thedigital label10 stores and displays label information and other information as more fully described below. The term “label information” includes source information indicating the source or origin of the product, product information describing the features contents, ingredients or use of the product, and manufacturer information that provides information about the product manufacturer. An example of source information is a brand name, logo (including animated logos), or slogan which identifies the source or origin, and authentication data for verifying the authenticity of the product. Examples of product information are instructions for the care or use of the product, and description of the contents or ingredients of the product. Examples of manufacturer information are the address (including an e-mail address) or telephone number for contacting the manufacturer, and the IP address of a web page for finding additional information about the company and its products.
• The digital label may also store consumer information or user information in addition to label information, and perform custom functions for the user. Consumer information is personal user information that affects the ownership, history, usage and effectiveness of the product. Examples of personal information are registration data, such as the name, address, contact information, weight, height, age, birth date, sex, DNA, allergies, medical and health conditions and history, scheduling information, personal preferences, diet, account information, other product usage data, etc.
• Thedigital label10 is particularly useful for products that do not otherwise include a display or microprocessor as an inherent feature of the product, but may also be used on products with a display or microprocessor. For example, in products that include a display as a functional feature of the product, the manufacturer may still use thedigital label10 of the present invention to provide a separate, dedicated display or microprocessor for displaying and transmitting trademarks, logos, brands, slogans, or other label and product information.
• Thedigital label10 according to the present invention provides a platform for manufacturers, retailers and end users to develop custom applications for thedigital label10 to expand the functionality of thedigital label10. In one embodiment, a processing circuit is configured to recognize and execute the user-defined applications. As used herein, the term “user-defined’ refers to users of the label and includes product manufacturers, retailers, and end users of the product. The user-defined applications allow the functionality of thedigital label10 to be expanded to perform functions for the user. Thus, the present invention extends the concept of a product label to include active devices that do more than present static information. thedigital labels10 according to various embodiments function as small computing devices that can be programmed to perform a wide variety of functions.

• The variety of applications that can be developed for the digital label is virtually limitless. A few exemplary applications for thedigital label10 are described below.
EXAMPLE 1Tag for Authentication and Product Tracking
• A recurring problem with branded and successful goods, such as designer and luxury clothing, handbags, accessories, jewelry, luggage; medication, liquor, and replacement parts, is the prevalence of counterfeit goods. As noted above, thedigital label10 of the present invention may store authentication data that enables purchasers of such goods to verify the authenticity of the products they purchase. The authentication data may comprise, for example, a serial number or code that can be used by the purchaser to authenticate genuine products. In some exemplary embodiments, the authentication data may be encrypted with a secret code to prevent counterfeiters from duplicatingdigital labels10. The authentication data may also change over time to make it more difficult to mimic. Thedigital label10 may also include a GPS receiver to enable tracking of the product in case that the product is lost or stolen.
• FIG. 6 illustrates a tag including adigital label10 for products such and luggage, handbags, and brief cases. Thedigital label10 stores an authentication number or serial number inmemory14 to enable users to authenticate genuine goods. Thememory14 for storing the authentication data may be a secure, tamper-proof memory to prevent tampering. The serial number may also be encrypted by the manufacturer with a secret key. For example, the serial number may be encrypted or signed with the manufacturer's private key and can be verified by the user by decrypting the serial number using the manufacturer's corresponding public key, which can be obtained from the manuufacturer's web site. If the authentication data is successfully decrypted, the user can be confident that the product is a genuine product so long as the manufacturer's private key has not been compromised. The user can also verify the authenticity of the product by sending the serial number to the manufacturer during product registration for verification. The authentication number could be read by the user from thedigital label10, or could be transmitted from thedigital label10 to the user's computer or other device. In some embodiments, thedigital label10 could transmit the authentication number via the Internet to a server maintained by the manufacturer for verification.
• Thedigital label10 can be programmed to change or update the serial number at a predetermined interval to make it more difficult to mimic.FIG. 7 illustrates adigital label10 that has a changing serial number. In this embodiment, thedigital label10 may include an algorithm for generating the authentication number that is known only to the product manufacturer. For example, the algorithm may comprises a function that generates an authentication code based on the current time and a secret key that is stored in a secure, tamper-proof memory.
• The tag or digital label may include aGPS system50 to enable tracking of the product. The global positioning system in thedigital label10 can determine and record the product's location periodically. This feature can be activated, for example, when the user is traveling to keep a history of the product's movement. The product manufacturer may maintain the web-based server to track products for its registered customers. An application program in thedigital label10 can report the current position of the product to the server at predetermined time intervals or in response to predetermined events or conditions.FIG. 8 illustrates an interface for a web-based tracking system that can be accessed by the user via the Internet to track the product.
EXAMPLE 2Product Container for Medications
• FIGS. 9 and 10 illustrate apharmaceutical container100 for medications including adigital label10 according to one embodiment of the invention. Thepharmaceutical container100 comprises abottle102 and acap104. Thedigital label10 is embedded in the walls of thebottle102. Thedigital label10 includes threebuttons22,24 and26 for receiving user input.Buttons22 and24 are used to navigate on-screen menus and to scroll through information on thedisplay16. Thecenter button26 is used to invoke the on-screen menu and make menu selections. Thedigital label10 includes anindicator lamp42 andweight sensor32, which are integrated with thebottle102. Theindicator lamp42 functions as an alertingdevice40 for alerting the user when it is time to take medication as described more fully below. Theweight sensor32 located in the bottom of theproduct container100 is used to detect the amount of remaining medication in the pharmaceutical container. Thedigital label10 also includes awireless communications interface18 for communicating with remote devices, such as acomputer150.
• Thedigital label10 stores and displays prescription data customized for the user as well as detailed drug data. The prescription data and drug data may be uploaded from acomputer150 to thedigital label10 by the manufacturer, pharmacist, doctor, or end user. In this example, the prescription data includes the medication, patient's name, and dosage information. Drug data may include information about medications, such as ingredients and chemical composition, possible side effects and drug interactions, precautions, warnings, government regulations, legal notices, disclaimers and disclosures, notifications, medication updates, recalls, etc. Such information is typically too voluminous to print on a conventional printed label, but can be easily stored and displayed on thedigital label10. Drug information including updates could also be transmitted to acomputer150 over thecommunications interface18 for viewing or printing. Thedigital label10 could also communicate with a web-based server, cell phone, personal digital assistant, etc., to transmit and receive information.
• An application program stored in thedigital label10 alerts the user when it is time to take medications, provides instructions on how to take medications, and records dosages taken by the user. The application program may also keep track of the remaining amount of medication and alert the user when it is time to have medications refilled. The amount of remaining medication may be determined from the input of theweight sensor32. Alternatively, the user may manually input usage information when the user takes medication to record such event. The user can be alerted to take or refill medication by activating theindicator lamp42 and displaying a message to the user on thedisplay16 as shown inFIG. 10. Thedigital label10 may also, if desired, send a message to the user's cell phone or computer when it is time to take or refill medications. For example, the application may send an email or text message to the user's cell phone or computer. When it is time to refill medications, thedigital label10 may also send a notification to the user's pharmacist to avoid the need for calling in prescriptions in advance.
• The application program may also collect and store usage information, such as the date and time that the medication is taken, the amount taken, the location, and environmental conditions (temperature, humidity, altitude, etc.) at the time medication is taken. Usage information may be determined based on input from the weight, temperature, humidity andother sensors32. Alternatively, the user can manually enter and record usage information using the availableuser input devices20. The usage information may be output to thedisplay16 or transmitted to acomputer150 or other external device, or processed along with information from other digital labels and products to coordinate multiple usage and consumption.
• The application program in thedigital label10 may cooperate with or integrate with medication management software oncomputer150 or other device, such as a cell phone, PDA, or web-based server system. Thedigital label10 can exchange prescription data, drug data and/or user data with thecomputer150 or other device. The medication management software on thecomputer150 can thus keep track of all medications being taken by the user and alert the user to potential problems and provide updates to thedigital label10 when necessary. The medication management software may include a database of pharmaceutical products. The medication management software can alert the user of potentially adverse drug interactions and side effects due to combinations of medications being taken. The medication management software may also include scheduling algorithms for suggesting times to take different medications to minimize drug interactions and maximize efficacy. A medication schedule can then be generated and transferred to thedigital label10 by the medication management software. The medication management software can also store information concerning the user's diet and suggest foods and beverages that should be used or avoided. Usage information indicating the dosages taken by the user can be transferred from thedigital label10 to the medication management software for evaluation and/or storage. This medication history may be transferred or uploaded to a physician. Alternatively, thedigital label10 can store medication history for later transfer to a computer at a physician's office.
• Several examples of the invention have been described. However, the present invention may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
